If you do not subscribe to cable or satellite TV service, then you will need an HDTV antenna to pull in your local HDTV stations. HDTV antennas can be as simple as a pair of souped up “rabbit ears”, or similar advanced reinforced roof rigs. What you need to pull all of your local stations will depend on factors such as You are close to the transmitter Tower and the local topography of the land in your area (hills, tall buildings etc.). To help determine the type of antenna You need, visit the AntennaWeb, a website sponsored by the Consumer Electronics Association and the Association of National Broadcasters.
